Did Brewer recommend the sauna? He didn't mention it to me. When did you last see him?
I've been having similar reactions to the protocol. Although I find some of my detox symptoms to be a little different we match up on most of them. There was one point I had to stop the meds; once I did I found I rebounded fairly quickly.
At one point I was feeling noticeably better so I thought I'd try a sauna for 10-15m. The 1st day went well, the 2nd day (a mistake in retrospect) really hit me hard. I ended up with swollen lymph nodes behind my ear and just felt terrible. When I get the courage to try that again I'll only do 1 day a week to begin with... Although I think I'll wait until my next appointment and ask about even using the sauna.
